Chunky? Well, I guess that would be one way of putting it. Compared to the Nikon and Canon cameras of the day, the K body cameras are actually a little on the slender side. I, for one, prefer the K series bodies to the smaller M series. My hands are pretty big and the leetle beety MX and ME bodies are a pain.
